3 times 3 = 9 plus the number 3 = 12.
How about: 1 times 91 plus 4 = 95 or 7 times 13 plus 4 = 95
6n + 7n (= 13n)
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26

18 is a solution to the equation 4 plus 7 times a number where the result is 9 times that number.
3 times 3 = 9 plus the number 3 = 12.
How about: 1 times 91 plus 4 = 95 or 7 times 13 plus 4 = 95
the number is 3 because 3 times 5 is 15 plus 2 is 17

6n + 7n = 13n
Because they are both multiples of two, so when they're added, the sum must be another multiple of two. (One group of twos plus another group of twos must be a new group of twos, just like one group of cows plus another group of cows must be a new group of cows.)

6n + 7n (= 13n)
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26
